In our cover story this month, WIRED's own Andy Greenberg dives into the cyber war Russia has been fighting with its neighbor, and how the tactics it honed there–how to take down a power grid, for instance–are a blueprint for what it could do to the United States. You should read it, and you should watch this video of what it looked like when hackers took over the actual mouse movements a power-grid computer.

Additionally, this week WIRED Security wrote about how Facebook is finally being transparent about its playbook for counterterrorism. We wrote about the frighteningly common screw up that left 198 million records exposed on the open website, for anyone (cough Russian hackers perhaps cough) to see. We also explained how worried you should be about that. We highlighted a new way for hackers to get into processors that involves, well, just the wave of a hand. And finally, 19 lawmakers sent President Trump a letter this week demanding he look into the Ukrainian power grid attack.
